This includes all non-zero digits, any zeros between significant digits, and trailing zeros only when there is a decimal point.<\/li>\n\n\n\n<li><strong>Identifying Significant Figures<\/strong>:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Non-Zero Digits<\/strong>: All non-zero digits (1-9) are considered significant. In the number 43.55, both 4 and 3 are non-zero, contributing to the significant figures.<\/li>\n\n\n\n<li><strong>Zeros<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>Leading Zeros<\/strong>: Zeros before the first non-zero digit are not significant. For example, in 0.0043, the zeros are not counted.<\/li>\n\n\n\n<li><strong>Captive Zeros<\/strong>: Zeros between non-zero digits are significant. For example, in 1002, the zero is significant.<\/li>\n\n\n\n<li><strong>Trailing Zeros<\/strong>: Zeros at the end of a number are significant only if there is a decimal point. For example, 100.0 has four significant figures, while 100 has one.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Application to 43.55<\/strong>:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The digits in 43.55 are 4, 3, 5, and 5.<\/li>\n\n\n\n<li>All these digits are non-zero; thus, they are all counted as significant figures.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Importance of Significant Figures<\/strong>:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Significant figures convey the certainty of a measurement. When performing calculations, such as addition or multiplication, the result should be expressed with the appropriate number of significant figures, based on the least precise measurement involved in the calculation.<\/li>\n<\/ul>\n\n\n\n<p>In summary, the number 43.55 has four significant figures because all its digits are non-zero and contribute to its overall precision.
